The International space station is constantly falling towards Earth under the pull of Earth's gravity (Just like any other object - gravity does not stop when you reach space!). However the Station is moving very fast horizontally and, as the Earth is a sphere, this means that as it falls its path takes it round the Earth in a circle - it is in "orbit".

This means that if you are in the space station you are falling as fast as gravity can pull you and therefore you do not feel the pull of gravity, making you weightless.

Does gravity affect the speed of light?

Gravity affects the fabric of space-time. So both space and time will be distorted.


What is the source of the centripetal force that keeps the International Space Station in orbit around the earth?

The centripetal force that keeps the International Space Station in orbit around the Earth is due to the gravitational pull between the Earth and the space station. This gravitational force causes the space station to constantly fall towards Earth, but its tangential velocity keeps it moving sideways, resulting in a stable orbit.


What two characteristics affect gravity?

The answer is that the two characteristics that affect gravity are mass and newtons. There is less gravity on the moon than on the earth. A space suit weighs 180 pounds on earth but on the moon it weighed way less than it was when it was on earth.


Is a bullet affected by gravity in space?

Yes, a bullet is affected by gravity in space. Gravity is a fundamental force that acts upon all objects with mass, so a bullet will still be pulled towards a larger mass like a planet in space due to gravity's influence.


Can space shuttles have gravity in them when in space?

Everything has a little of its own gravity, but you would have to be very massive to make just a little. Space shuttles have gravity, but it is almost too small to measure or have any effect on anything large. Some large asteroids have enough mass to make a small orbit. If you through a tennis ball on one of them, it might loop back and hit you on your head.

Does the earth gravity affect the astronaut in space?

If he is aboard something that's in Earth-orbit, like the International Space Station or the Space Shuttle, then Earth's gravity is what's keeping him in orbit.

Which force keeps the space station in orbit?

The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.

What anastronaut working in Space near the International space station says she feel weightless. What does she mean Does the astronaut no have weight?

It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.


Why doesn't a space station have any moons?

Compared to a planet a space station is tiny. While all objects with mass gave gravity, that of a space station is negligible, and certainly could not keep a moon in orbit.
